Description

Alkaline ion water purifier technical field

TECHNICAL FIELD The present invention relates to an alkali ion water purifier capable of supplying ionized ionized water and acidic ionized water by ionizing tap water supplied from tap water, and more particularly to a type provided in the middle of a water pipe, a so-called built-in type. It relates to a bright type alkali ion water conditioner. Background art

book

An Al-Rion water conditioner that generates Al-Lion water and acidic I-ion water from tap water uses an ion exchange membrane between the positive and negative electrodes and utilizes the electrolysis of water to form Al-Lion water. Some are separated and produced from acid ion water. In addition, such an AL-RION water conditioner is designed to take water from a water tap (faucet) and discharge AL-RION water and acidic ionic water from a dedicated water outlet, and install the main unit on a sink. There are types. In addition, there is a so-called built-in type, in which the main unit is installed in the undersink, which has a dedicated cull for water intake and water spouting.

By opening, tap water is passed through the raw water pipe and supplied to the electrolytic cell, where alkaline water and acidic water are generated. Then, the alkaline water generated in the electrolytic cell is discharged through the water discharge pipe, and the acidic water is discharged through the acid water discharge pipe. In addition, when the user closes the faucet, the flow of water from the raw water pipe is stopped, and the discharge of alkaline water is stopped.

In this type of water purifier, when the water discharge of the water is stopped, the acidic water drainage pipe from which the acidic water is drained is open to the atmosphere. A water pressure difference occurs between the water side and the water side. Then, the ion exchange placed in the electrolytic cell The exchange membrane has a problem that it is extremely thin and has a small hole for passing hydrogen ions, so that the membrane is easily damaged due to such a difference in water pressure.

As shown in the figure, tap water is ionized inside the water purifier body 11 constituting the outer frame of the water force water purifier 10 of the present embodiment, and alkaline ionized water and acidic ionized water are formed therein. A plurality of electrolytic cells 12 to be generated are held. The water purifier body 11 also has a tap water inlet 11a for introducing tap water from the raw water pipe into the inside, and an AL water outlet for discharging the AL water produced in the electrolytic cell 12. A water spout 11b and an acid water outlet 11c for discharging acid ion water are provided.

Specifically, a tap water supply pipe 13 communicating with the tap water inlet 11 a of the water purifier body 11 is connected to the lower end side of each electrolytic tank 12, and the upper end of the electrolytic tank 12 On the side of the electrolysis tank 1 2, there are an AL water discharge pipe 14 communicating with the AL water discharge port 1 1 b and an acid water discharge pipe 15 communicating with the acid water discharge port 1 1 c. Each is connected to the upper end. Each of the pipes 13, 14, and 15 is fixed to the water conditioner main body 11, so that each electrolytic cell 12 is held in the water conditioner main body 11.

An ion exchange membrane 16 is fixed in each electrolytic cell 12, and the ion exchange membrane 16 divides the inside of the electrolytic cell 12 into two spaces 12 a and 12 b. You. Further, a pair of electrodes 17a and 17 are provided in a region facing the ion exchange membrane 16 in the electrolytic cell 12 respectively, and each electrode 17a and 17b is provided with a water conditioner. The terminal part 18 provided on the main body 11 is connected to the connection wiring 19. In the present embodiment, each of the electrodes 17a and 17b is, for example, a mesh-shaped plastic. One surface of a fixing member 20 which is formed of a sheet or the like and has a size equivalent to an ion exchange membrane. Is attached to each. Then, these fixing members 20 are arranged so as to sandwich the ion exchange membrane 16 in each of the spaces 12 a and 12 b, so that the electrode 17 a is formed in a region opposed to the ion exchange membrane 16. , 17b are provided.

At least a part of the region facing the ion exchange membrane 16 of the electrolytic cell 12, in the present embodiment, the whole of the electrolytic cell 12 is formed of a flexible film having a predetermined flexibility. . For example, in the present embodiment, the electrolytic cell 12 is formed of a plastic sheet having a thickness of about 0.3 mm.

Further, tap water is supplied to the inside of the water conditioner main body 11 in which such a plurality of electrolytic baths 12 are held, that is, the space between each electrolytic bath 12 and the water conditioner main body 11, Each electrolytic cell 12 is held in the tap water (retained water) 21 stored in the body 11 of the regulator. Further, in the water adjusting pack main body 11, a part of the area not in contact with the electrolytic cell 12, for example, in this embodiment, an air part 2 2 in which air remains at the upper part of the acidic water discharge pipe 15. Exists. The water conditioner main body 11 into which the tap water is supplied as described above needs to be formed of a material having rigidity enough to withstand the water pressure of the tap water, for example, stainless steel or the like.

Further, in this embodiment, the stored water 21 is a supply of tap water from the tap water inlet 11 a of the water purifier body 11 along with the electrolytic cell 12 into the water purifier body 11. is there. That is, at the end of the tap water supply pipe 13, a minute communication hole 23 communicating with the water conditioner main body 11 is provided, and the water conditioner main body 1 is connected through the communication hole 23. Tap water (reserved water 21) is supplied within 1. In the present embodiment, a fine communication hole 24 communicating with the water conditioner main body 11 is also provided at the distal end of the acidic water discharge pipe 15, and the stored water 21 is formed by the communication hole. The water is discharged to the acidic water discharge pipe 15 through 24. For this reason, in the present embodiment, the upper part of the acidic water discharge pipe 15 in the water conditioner main body 11, that is, the upper side of the communication hole 24 becomes the air part 22 in which air remains. ing.

In the present embodiment, the stored water 21 is discharged to the outside together with the acidic water through the communication hole 24. Of course, the stored water discharge port for discharging the stored water 21 to the outside is provided. It may be provided in the water conditioner body 11 so that it is discharged to the outside separately from the acidic ionized water. As shown in Fig. 3, such an alkali ion water purifier 10 is connected to a tap water supply pipe 13 and a water pipe 110A on the raw water side, and an It is connected to the water pipe 110B on the faucet 100 side. One end of the acidic water discharge pipe 15 is connected to a discharge port 120 from which the acidic ionic water generated by the electrolytic cell 12 is discharged. An electromagnetic valve 3 is provided in the middle of the acidic water discharge pipe 15, and the discharge amount of the acidic water is controlled by opening and closing the electromagnetic pulp 30. For example, in the present embodiment, a flow switch 40 is provided at a connection portion between the water discharge pipe 14 and the water pipe 110B, and electromagnetic pulp is provided based on a signal from the flow switch 40. 30 is opened and closed. Further, such control of the flow rate switch 40 and the electromagnetic valve 30 or control of the voltage supplied to the electrodes 17a and 17b in each electrolytic cell 12 is not shown in FIG. Is controlled by the department. Hereinafter, the operation of such an alkali ion water conditioner will be described.

As described above, since the alkali ion water conditioner 10 is provided in the middle of the water pipe, tap water is always supplied to the electrolytic tank 12 from the water supply pipe 13 at a predetermined pressure. ing. Then, when the user opens the faucet 101 provided in the faucet 100, the Al-Lion water generated in the electrolytic cell 12 is discharged from the faucet 1 through the Al-Ly water spouting pipe 14. It starts to be supplied at a predetermined flow rate from 00. At the same time, the flow switch 40 provided between the alkaline water discharge pipe 14 and the water pipe 110B detects that the AL-ion water has begun to flow. A predetermined voltage is applied between the electrodes 17a and 17b in the electrolytic cell 12 based on the signal. Further, the electromagnetic valve 30 provided in the acidic water discharge pipe 15 is opened, and the acidic ion water is discharged from the discharge port 120.

Here, the tap water supplied into the electrolytic cell 12 from the lower end side of the electrolytic cell 12 via the tap water supply pipe 13 is supplied to the space 12 a on both sides separated by the ion exchange membrane 16. Flow into 1 and 2 respectively. Since a predetermined voltage is applied between both electrodes 17a and 17b, when passing through the electrolytic cell 12, that is, between the ion exchange membrane 16 and the electrode, Water is ionized into hydrogen ions H + and hydroxyl ions OH—, and hydrogen ions H + collect in one space via the ion exchange membrane 16 to generate alkali ion water and acidic ion water. That is, one electrode of two spaces (shade Pole) In the space 1 2 b on the 17 b side, hydrogen ions H + force S gather through the ion exchange membrane 16, and tap water (2 H ₂ O) is converted into H ₂ + 2 by electrons (2 e—). The water is adjusted to OH- and alkaline ionized water is generated. On the other hand, + the electrode (anode) 1 7 a side of the space 1 2 a, tap water (2 H ₂ O) is water conditioner to _{0 2 + 4 H + + 4} e, acidic ionized water is produced. In this way, the tap water is continuously ionized when passing through the electrolytic cell 12, and the alkaline ion water generated thereby is supplied from the faucet 100 and the acidic ion water is discharged from the outlet. Emitted from 120.

Also, when the user closes the faucet 101, the supply of the alkaline ionized water is stopped. When the flow in the alkaline water discharge pipe 14 is stopped, the acid water is stopped by the signal of the flow rate switch 40. The electromagnetic pulp 30 provided in the discharge pipe 15 is closed, and the discharge of the acidic water is also stopped.

Here, the time at which the flow in the water discharge pipe 14 is generated or stopped by the opening and closing of the faucet 101, and the time at which the flow rate switch 40 detects it and the electromagnetic valve 30 is opened and closed. And there is a slight time lag. Due to the inertial action of the flowing water caused by this time lag, a difference occurs between the internal pressure of the space 12 b on the alkali ion water side and the space 12 a of the acid ion water side in the electrolytic cell 12. Since the ion exchange membrane has, for example, a thickness of about 12 m, the pressure difference may cause the ion exchange membrane 16 to be deformed and damaged.

However, in the present embodiment, since the electrolytic cell 12 is formed of a flexible membrane, for example, when the faucet 101 is opened, a pressure difference is generated between the two spaces 12 a and 12 b. However, as shown in FIG. 4, this pressure difference is absorbed by the electrolytic cell 12 itself deforming inward, so that the ion exchange membrane 16 can be prevented from being damaged by deformation. When the faucet 101 is closed, the internal pressure difference is absorbed by the electrolytic cell 12 itself deforming outward.

Further, in the electrolytic cell 12, as described above, the fixing member 20 is provided so as to be sandwiched between the electrodes 17 a and 17 b on the other side and the ion exchange membrane 16. ing. That is, the ion exchange membrane 16 is sandwiched by these fixing members 20. Accordingly, the deformation of the ion exchange membrane 16 is also suppressed by these fixing members 20, and the breakage of the ion exchange membrane 16 due to the internal pressure difference of the electrolytic cell 12 is more reliably prevented. be able to. Here, the fixing member 20 is, for example, a spacer that can keep a constant interval between two parts or the like. In the present embodiment, the entire electrolytic cell 12 is formed of a flexible film. Of course, if the pressure difference in the electrolytic cell 12 can be absorbed, the flexible portion made of the flexible film can be used as the electrolytic cell 12. Alternatively, it may be provided in a part of the region facing the ion exchange membrane.

In addition, in order to absorb the pressure difference between the two spaces 12a and 12b due to the deformation of the electrolytic cell 12, the electric angle tank 12 needs to have relatively high flexibility. It is preferable to have more flexibility than the ion exchange membrane 16. In order to satisfy this condition, the electrolytic cell 12 is formed of a flexible film made of a relatively thin plastic film. Therefore, the electrolytic cell 12 itself withstands the pressure of tap water supplied into the electrolytic cell 12 via the tap water supply pipe 13, for example, a pressure of about 1 to 6 kg / cm ^2. There is a risk of being destroyed without being crushed.

However, in the present embodiment, when tap water is supplied into the electrolytic cell 12 through the tap water supply pipe 13, the tap water supply main body 1 is connected to the communication hole 23 at the tip of the tap water supply pipe 13. Tap water is also supplied to the inside 1, and each electrolytic cell 12 is held in the stored water 21 stored in the water purifier body 11. For this reason, the pressure of the stored water 21 in the water conditioner main body 11 is maintained at substantially the same pressure as the tap water supplied to the electrolytic cell 12, and the inner surface of the electrolytic cell 12 is Approximately the same water pressure is applied. Therefore, even when relatively high pressure is applied to the inner surface of the electrolytic cell 12 by the tap water supplied into the electrolytic cell 12, substantially the same pressure is applied to the outer surface of the electrolytic layer 12. Thus, the electrolytic cell 12 itself is not damaged by deformation due to a change in water pressure.

Further, in the present embodiment, the stored water 21 is discharged to the outside together with the acidic ion water from the communication hole 24 provided in the acidic water discharge pipe 15. That is, the water purifier body 11 is not fully filled with tap water, and an air portion 22 in which air remains is present above the communication hole 24. Therefore, the deformation of the electrolytic cell 12 due to the pressure difference in the electrolytic cell 12 described above is not hindered by the stored water 21, and the ion exchange membrane 16 can be prevented from being damaged.

That is, as described above, when the electrolytic cell 12 is deformed due to the pressure difference in the electrolytic cell 12, the volume in the water conditioner main body 11 changes. At this time, the stored water 2 1 itself is substantially When the water storage unit 11 is fully filled with the stored water, the stored water 21 prevents the electrolytic cell 12 from being deformed. However, in the present embodiment, since the air part 22 is present in the water conditioner main body 11 and the volume of the air part 22 changes when the electrolytic cell 12 is deformed, the deformation of the electrolytic cell 12 is performed. Is not disturbed. Therefore, by providing the air part 22 in the water conditioner body 11, damage to the ion exchange membrane 16 can be prevented more reliably.

The volume of the air portion 22 is not particularly limited, but is preferably about 20 to 30% of the volume in the water conditioner main body 11.

As described above, in the alkali ion water purifier 10 of the present embodiment, even if tap water is supplied at a relatively high water pressure, the ion exchange membrane 16 and the electrolytic cell 12 are not damaged, so that a predetermined number of By arranging tanks 12 side by side, at a flow rate equivalent to that of tap water, for example, about 20 to 30 (L / min) for general household use, and about 100 (L / min) for commercial use Alcalyon water can be supplied to users.

Therefore, the allion water generated by the allion water dispenser 10 can be supplied to a water heater such as an electric water heater and provided to the user as hot water. Can be used for bathing and showering. In the case where alkaline ionized water is supplied from the alkali ion water conditioner 10 to the water heater

However, the water pressure of the water supplied to the water heater is slightly reduced. For this reason, for example, as shown in FIG. 5, by providing a flow rate adjusting member 50 in the acidic water discharge pipe 15 to block a part of this discharge flow path, the alkali ion supplied to the water heater is provided. The water pressure of the water may be adjusted.

In the above-described Al-Rion water conditioner 10, the ratio of Al-Lion water to acidic ionic water is set to about 10 to 2 by adjusting the internal flow resistance and the like. Therefore, the discharge of acid ion water is extremely small as compared with the conventional one-to-one system, but this ratio can be set as appropriate.

Further, in the alkali ion water purifier 10 of the present embodiment, the acidic ion water is allowed to flow to the discharge pipe without being used, but for example, the acidic ion water can be used by storing it in a dedicated tank or the like. You can also In this case, it is desirable to discharge the stored water 21 outside the acidic ionized water separately. Further, in the Al-Rion water conditioner 10 of the present embodiment, the plurality of electrolytic cells 12 are arranged side by side at predetermined intervals in the water conditioner main body 11, but the invention is not particularly limited to this. Instead, for example, the electrolytic cells 12 may be juxtaposed so that the outer peripheral surfaces are in contact with each other without leaving a space between the adjacent electrolytic cells 12. Even if the adjacent electrolyzers 12 are arranged side by side without leaving an interval as described above, the pressure difference in the electrolyzer can be absorbed by the flexible membrane that is not in contact with the electrolyzer, and the adjustment can be performed. Water main unit 1 1 can be downsized

As described above, in the Al-Lion water purifier 10 of the present embodiment, the pressure difference caused by the opening and closing of the faucet 101 can be absorbed by the flexible membrane of the electrolytic cell 12A. However, alkaline ionized water can be spouted at the same flow rate as tap water. In addition, in the conventional Al-Lion water purifier, the discharge ratio of Al-Lion water and acidic ionic water is about 1 to 1, and the discharge of acid-ion water (discarded water) is accompanied by the discharge of Al-Lion water. Although it was about half, the alkali ion water purifier 10 of the present embodiment has an advantage that the discharge amount of the acidic ion water can be extremely reduced. On the other hand, the structure of the electrolytic cell is not limited to that described above. For example, an alkaline ionizer using an electrolytic cell 12A as shown in FIG. 6 may be configured. In FIG. 6, the same members as those in the first embodiment described above are denoted by the same reference numerals, and redundant description will be omitted.

As shown in FIG. 6, the electrolytic cell 12 A is provided with an ion exchange membrane 16 and a pair of electrodes 17 a and 17 b so as to face the ion exchange membrane 16. . Further, the electrolytic cell 12A is entirely formed of a flexible film having a predetermined flexibility, as in Embodiment 1 described above.

Each of the electrodes 17a and 17b is fixed by four fixing members 2OA provided on the inner surface of the electrolytic cell 12A. The fixing member 2OA is provided between the inner surface of the electrolytic cell 12A and the electrodes 17a, 17b, and has a cylindrical spacer 20a forming a gap of 1 mm, for example. And a sleeper 20b having a cylindrical shape sandwiching the electrodes 17a and 17b between the spacer 20a and a spacer 20a and a sleeve 20b. With a rivet 20 c fixed at one end to the electrolytic cell 12 A Have been. .

Further, the ion exchange membrane 16 is sandwiched between a sleeve 20b holding the electrode 17a and a sleeve 20b holding the electrode 17b. That is, the ion exchange membrane 16 is sandwiched at four places by a sleeve 20b for fixing the electrodes 17a and 17b, whereby each of the electrodes 17a and 17b is It is provided separated from the ion exchange membrane 16 by a predetermined distance. At this time, in the present embodiment, the gap between each of the electrodes 17a and 17b and the ion exchange membrane 16 is, for example, 3 mm.

Even when the ion exchange membrane 16 is sandwiched at points by the four fixing members 2OA, such an electrolytic cell 12A is not affected by a pressure difference caused by opening and closing the faucet 101. Since the force difference can be absorbed by the flexible membrane, the ion exchange membrane 16 can be prevented from being damaged.

That is, in Embodiment 1 described above, the deformation of the ion exchange membrane 16 is suppressed by sandwiching the ion exchange membrane 16 using the mesh-shaped fixing member 20. However, the implementation of the present invention is not limited to the structure of the electrolytic cell and the fixing member for holding the ion exchange membrane 16 in the electrolytic cell or the fixing method. For example, as in the present embodiment, The use of the four fixing members 2 OA can also suppress the deformation of the ion exchange membrane 16.

As described above, even when an Al-forced water conditioner using the electrolytic cell 12 A as described above is configured, the pressure generated by opening and closing the faucet 101 is the same as in the first embodiment. Since the difference can be absorbed by the flexible membrane of the electrolytic cell 12 A, it is possible to discharge the alkaline ionized water at the same flow rate as tap water, and the discharge amount of the acidic ionized water can be extremely reduced. There is.

(Embodiment 2)

FIG. 7 is a diagram showing a schematic configuration of an alkali ion water purifier according to Embodiment 2 of the present invention, and FIG. 8 is a control system of an Al-Rion water purifier according to Embodiment 2 of the present invention. FIG. In the second embodiment as well, at the time of discharging the standard alkaline water, the ratio of the alkaline water to the acidic water is 10: 2 due to the structural design of the alkaline water ionizer. It is set to be. The present embodiment is an example in which the flow control valve 30A is controlled by the control of the control device 60 such that the discharge amount of the acidic ion water with respect to the discharge amount of the alkaline ion water becomes a predetermined ratio.

In such control, the present embodiment is different from the above-described first embodiment in that a flow sensor 40B is provided in the middle of the acidic water discharge pipe 15. Further, in the above-described first embodiment, the electromagnetic valve 30 having a function of opening and closing based on a predetermined signal is employed. However, in the present embodiment, a flow rate adjusting valve 3 OA that can further adjust the flow rate is used. They differ in their adoption.

As shown in the figure, the control device 60 is installed outside the water conditioner body 11 and electrically connected to a terminal 18 provided on the water conditioner body 11 and connection wiring (not shown). And controls the voltage supplied to the electrodes 17a and 17b in each electrolytic cell 12. The configuration of the control device 60 is not limited as long as it can perform calculations based on input signals and has a function of outputting signals based on the calculation results. The control device 60 is installed outside the water purifier main body 11, but may be held inside the water purifier main body 11.

Note that, in the present embodiment, other configurations than the above-described configuration are the same as those of the above-described first embodiment, and a description thereof will be omitted.

In the AL-RION water purifier 10 A having such a configuration, when the user opens the faucet 101 provided in the faucet 100, the AL-RION generated in the electrolytic cell 12 is opened. The ON water starts to be spouted at a predetermined flow rate from the faucet 100 via the water spouting pipe 14. At the same time, the flow sensor 4 OA provided between the water discharge pipe 14 and the water pipe 110 B detects that the alkaline ionized water has begun to flow, and the flow sensor 4 OA A predetermined voltage is applied between the electrodes 17a and 17b in the electrolytic cell 12 based on the signal from Further, the amount of acidic ion water discharged from the outlet 120 is adjusted by driving the flow rate adjusting valve 3 OA provided in the acidic water discharge pipe 15. That is, as in the example shown in FIG. 8, the control device 60 obtains the amount of discharged alkaline ionized water detected by the flow rate sensor 4OA, and always discharges the discharged alkaline ionized water even if the discharged amount changes. The flow control pulp 30A is driven by calculating so that the amount of acidic ion water is about 20% of the amount of alkali ion water. Also, In the present embodiment, the control device 60 obtains the amount of acidic ionic water detected by the flow sensor 40 B provided in the acidic water discharge pipe 15, and controls the flow control valve 3 OA based on the discharged amount. Since feed-pack control is used, control can be performed while confirming whether or not the amount of acid ion water actually discharged is about 20% of the amount of alkali ion water.

The numerical value of 20% of the amount of alkaline ionized water here is a design value from the beginning, and the apparatus of the present embodiment discharges acidic force water at a predetermined water-concentration concentration while maintaining the acid ion elongation. This is a value that can keep the emission amount to a minimum, but is not limited to this, and can be changed according to the equipment standard.

In addition, the discharge rate of alkaline ionized water and acidic ionized water is about 1 to 1 in the conventional Al-Lion water conditioner, and the discharge of acid-ion water (discarded water) is reduced by half with the discharge of Al-Lion water. Although the degree of discharge of the acidic ion water can be extremely reduced according to the Al-Lion water purifier 10 A of the present embodiment, as described above, in the present embodiment, The advantage is that this ratio does not change even when the amount of spouted Li-ion water is very small, and wasteful acid ion water is not always discharged.

In the control example described above, the control device 60 acquires the flow rates detected by the flow sensors 40A and 4OB, respectively. However, the present invention is not limited to this. For example, the flow sensors 40A and 40B May be controlled so as to notify the control device 60 of the detected flow rate. Further, similarly to Embodiment 1 described above, when the user closes the faucet 101, the supply of the alkaline water is stopped, and accordingly, the flow in the hydraulic water discharge pipe 14 stops. The flow control valve 3 OA provided in the acidic water discharge pipe 15 is driven by the signal of the flow sensor 4 OA, and the discharge of the acidic water is stopped.

At this time, if the amount of the acidic ionized water to be discharged is always controlled to be about 20% of the total amount of the ionized water, the electrolytic cell 12 is easily damaged. That is, by maintaining the amount of alkaline ionized water and the amount of acidic ionic water at a discharge ratio of 10 to 2, in the electrolytic cell 12, the space 1 b on the Al-ion water side and the space 1 b on the acid-ion water side There will be a difference between 2a and the internal pressure. Since the ion exchange membrane 16 has, for example, a film thickness of about 11211, the pressure difference may cause the ion exchange membrane 16 to be deformed and damaged. However, in this embodiment, since the electrolytic cell 12 is formed of a flexible film, for example, when the faucet 101 is opened as described above, a pressure difference is generated between the two spaces 12a and 12b. Even in the case where the pressure difference occurs, similarly to Embodiment 1 described above, since the electrolytic cell 12 itself deforms inward, this pressure difference is absorbed, so that the ion exchange membrane 16 can be prevented from being damaged by deformation. it can. Therefore, the pressure difference caused by maintaining the discharge ratio of the amount of the alkali ion water and the amount of the acidic ion water to 10 to 2 as described above can be relatively easily absorbed.

As described above, in the alkali ion water purifier 1 OA of the present embodiment, the discharge amount of the acidic ion water with respect to the discharge amount of the alkaline ion water can always be maintained at a predetermined ratio. The discharge of acidic ionized water can be minimized, and the water conditioning concentration of Alion deionized water, which changes due to fluctuations in the amount of spouted Alion deionized water, can be kept constant. In the water pressure regulator 10A of the present embodiment, since the electrolytic cell 12 is formed of a flexible film having a predetermined flexibility, the discharge ratio of the alkaline ionized water and the acidic ionized water is determined. The internal pressure difference caused by maintaining a constant ratio can be easily absorbed.

As described above, one embodiment of the present invention has been described. However, the basic configuration of the present invention is not limited to the above, and the following modified configuration is possible.

For example, the control system shown in FIG. 8 is an example, and any control system may be used as long as it controls the discharge amount of acid ion water in accordance with the amount of spouted water. It is not always necessary to provide the flow sensor 40B. That is, even when the flow rate sensor 40B is not provided, the same control as the above-described control can be executed except that the feedback control is not performed.

Also, even when the flow sensor 40B is provided, it is not always necessary to perform feedback control. For example, the control device 60 obtains the flow rates of the flow sensors 4OA and 40B, and The flow control valve 3OA may be controlled so that the ratio of the flow control valve 3OA falls within a predetermined range.

Also, the controller 6Q does not need to constantly control the flow control pulp 3OA, and the ratio of the discharge amount of alkaline ion water to the discharge amount of acidic ion water is, for example, 10: 2 ± 1. Control may be performed only when the value is out of the range of 0% to 20%.

Further, the drive of the flow control valve 30A performed by the control device 60 may be a stepwise drive instead of a continuous drive. That is, the discharge amount of the acidic ionized water may be such that the discharge amount of the alkaline ionized water is set at a plurality of levels, and the discharge amount is controlled stepwise according to the level.

(Embodiment 3)

FIG. 9 is a schematic block diagram showing a control system of an Al-Li-ion water purifier according to Embodiment 3 of the present invention.

In this embodiment, based on the configuration shown in Fig. 3, when the discharge of alkaline ionized water stops, the electrolytic water on the acidic ion water side 12a remaining in the electrolytic cell 12 is replaced with tap water. FIG.

In such control, the present embodiment is different from the above-described first embodiment in that a tap water replacement means 50 is provided in the control section 60B as shown in FIG. The control section 60 B mainly controls the power supply system including the application of voltage to the electrodes 17 a and 17, the flow switch 40 and the electromagnetic pulp 30, and the tap water replacement means 50 0 Controls the flow switch 40 and the electromagnetic pulp 30 to replace the water on the acidic ion water side 12a. Then, the tap water replacement means 50 delays the operation of closing the electromagnetic valve 30 until the discharge of the acidic ion water reaches a predetermined amount after detecting the stoppage of the discharge of the ionized water. Has functions. The configuration of the control section 60B is not limited as long as it has a function capable of controlling the operation of all or a part of the peripheral device based on an input signal or an output signal. For example, the control unit 60B includes a control device including a general microprocessor and a memory. · In the present embodiment, since the configuration other than the above-described configuration is the same as that of the above-described first embodiment, the description thereof is omitted.

In such an AL-RION water conditioner 10B, when the faucet 101 is stopped, the control unit 60B indicates that the discharge of the AL-RION water detected by the flow switch 40 is stopped. Get the signal. Thus, the application of the voltage to the electrodes 17a and 17b is stopped. On the other hand, the tap water replacement means 50 discharges acidic ionized water based on the acquired signal. The operation of closing the electromagnetic pulp 30 is delayed until a predetermined amount is reached. Thus, the introduction of tap water to the acidic ionized water side 12a is continued while the introduction of tap water to the alkaline water side 12b in the electrolytic cell 12 is stopped. -Then, the tap water replacement means 50 sends an f | signal to the electromagnetic valve 30 so as to stop the discharge of the acidic ion water after a predetermined amount of the acidic ion water is discharged from the outlet 120. I do. Upon receiving the instruction signal, the electromagnetic valve 30 closes the flow path on the acidic water discharge pipe 15. As a result, all the electrolytic water ′ on the acidic ionized water side 12 a in the electrolytic cell 12 is replaced with tap water. In the present embodiment, the retention amount on the acidic ion water side 12a is about 0.45 liter, and by delaying about 15 seconds, the water in the acidic ion water side 12a is completely replaced with tap water. Have been.

As described above, in the Al-Lion water conditioner 10 B of the present embodiment, when the spouting of the Al-Lion water stops, the side of the acidic ionized water 12a left in the electrolytic cell 12 is stopped. Only the electrolyzed water can be flushed with the tap water, and the electrolyzed water can be replaced with the tap water. For this reason, the electrolyzed water remaining in the electrolyzed water side 12 b in the electrolyzer 12 is maintained as it is without being changed to acidic ionized water or the like. Therefore, for example, when the user opens the faucet again, it becomes possible to use Al-Ion deionized water immediately without waiting for waste water.

The embodiment of the present invention has been described above. However, the basic configuration of the present invention is not limited to the above, and the following modified configurations are possible.

The control system shown in FIG. 9 is an example. For example, a flow switch (hereinafter, referred to as a flow switch 40a; not shown) for detecting the discharge amount of the acidic ion water is provided to the acidic water discharge pipe 15. Accordingly, the control unit 60B obtains the actual discharge amount of the acidic ion water detected by the flow rate switch 40a, and the tap water replacing means 50 actually performs the acidic ion water 12a After confirming that the water has been replaced, the electromagnetic valve 30 may be controlled. That is, for example, the tap water replacement means 50 sends an instruction signal to the electromagnetic valve 30 at a timing when the integrated value of the discharge amount of the acidic ionic water detected by the flow rate switch 40a becomes a predetermined amount. do it. Accordingly, it is possible to confirm whether or not the amount of the acidic ion water to be discharged after the faucet 101 is stopped is a predetermined amount, and to control reliably while adjusting the degree of opening and closing of the electromagnetic valve 30. it can. The signals detected by the flow switches 40 and 40a do not necessarily need to be acquired by the control unit 60B. When the flow switch 40 or 40a detects the signal, the control unit 60 B may be notified.

In the control system described above, the control unit 60B and the tap water replacement means 50 are provided outside the alkali ion water conditioner 10B. However, the present invention is not limited to this. It may be provided inside 10 B. -In addition, the third embodiment described above may be applied to the second embodiment as it is.

(Embodiment 4)

FIG. 10 is a diagram showing a schematic configuration of an Al-Lion water purifier according to Embodiment 4 of the present invention. FIG. 11 is an Al-Lion water purifier according to Embodiment 4 of the present invention. FIG. 12 is a schematic block diagram showing the control system of FIG. 12, and FIG. 12 is a diagram showing an operation example of the electrode and the electromagnetic pulp according to Embodiment 4 of the present invention.

In the present embodiment, the polarity of the voltage applied to the electrodes 17a and 17 is inverted at each use interval of the alkaline ionized water, and the water discharge pipe 14 and the acidic water discharge pipe 15 are connected to each other. Example of controlling to reverse the connection flow path connected to

C, oh.

In such control, in the present embodiment, the water discharge pipe 14 is connected to the space 12b and the acid water discharge pipe 15 is connected to the space 12a. The first connecting pipe 14A is connected via the first connecting pipe 14A and the second connecting pipe 15B which is branched from the upstream side and communicates with the second connecting pipe 15A. 4B, and the second connecting pipe 15A is provided with a fourth connecting pipe 15B that branches off from the upstream side and communicates with the first connecting pipe 14A. This is different from the first embodiment described above. In the middle of the first to fourth connecting pipes 14A, 14B, 15A and 15B, solenoid valves 31 to 34 are provided, and a faucet 100 is provided. Alternatively, the flow path connected to the discharge port 120 is controlled by opening and closing the electromagnetic pulp 31 to 34.

The present embodiment also differs from the above-described first embodiment in that the control unit 60C is provided with an inversion means 5OA as shown in FIG. This control unit 60 C is mainly As a body, the power supply system including the application of voltage to the electrodes 17a and 17b, the flow switch 40, the electromagnetic valves 31 to 34, and the electromagnetic pulp 30 are controlled. Then, the inversion means 5 OA inverts the polarity of the voltage applied to the electrodes 17 a and 17 b, and switches the faucet 10 from any of the spaces 12 a and 12 b in the electrolytic cell 12. It has a function of inverting the connection flow path leading to 0 or the connection flow path leading from any one of the spaces 12 a and 12 b in the electrolytic cell 12 to the outlet 120. The configuration of the control unit 60C is not limited as long as it has a function capable of controlling the operation of all or a part of the peripheral device based on an input signal or an output signal. Absent. For example, the control unit 60C includes a control device including a general microprocessor and a memory.

When the faucet 101 is opened in such an Al-Rion water purifier 10C, the control unit 60C sends a signal indicating the start of spouting of the Al-Rion water detected by the flow switch 40. After obtaining the voltage, a predetermined voltage is applied between the electrodes 17a and 17b, and the electromagnetic valve 30 is opened so that the acidic ion water is discharged from the discharge port 120. At this time, as shown in the “first switching state” in FIG. 12, a positive voltage is applied to the electrode 17a, a voltage is applied to the electrode 17b, and the electromagnetic pulp 3 1 and 32 are open, and the solenoid valves 33 and 34 are closed. That is, the first connection pipe 14A and the second connection pipe 15A are open (hereinafter, referred to as a "first switching state").

Here, when the faucet 101 is closed by the user, the discharge of the alkaline ionized water is stopped, and the polarity of the voltage applied to the electrodes 17a and 17b into the electrolytic cell 12 is changed. The solenoid valves 31 to 34 are opened and closed so that the connection flow paths to the water discharge pipe 14 and the acid water discharge pipe 15 connected from the electrolytic cell 12 are inverted. Controlled. That is, when the control unit 60C obtains a signal indicating the stoppage of the water discharge of the AL force water detected by the flow rate switch 40, the reversing means 50A performs the “second switching state” of FIG. As shown in the figure, the polarity of the applied voltage is reversed so that the electrode 17a is the negative electrode and the electrode 17 is the positive electrode, and the solenoid valve is 33 and 34 are opened, and the flow paths passing through the alkaline water and the acidic ion water are reversed so that the electromagnetic valves 31 and 32 are closed.

At this time, the third connection pipe 14 B and the fourth connection pipe 15 B are in an open state (hereinafter, referred to as a “second switching state”), and the connection is made in conjunction with the reversal of the polarity. The flow path is also inverted from the first switching state to the second switching state. Thereby, when tap water is introduced again into the electrolytic cell 12, alkaline ionized water is generated in the space 12 a and acidic ionized water is generated in the space 12 b. Accordingly, Alion water is discharged from the faucet 100 through the Alion water spouting pipe 14 via the second connecting pipe 15A and the fourth connecting pipe 15B, and the acid ion is discharged. Water is discharged from the outlet 120 through the acidic water discharge pipe 15 via the first connection pipe 14A and the third connection pipe 14B.

Further, the control unit 60C obtains a signal indicating the stop of the discharge of the ionized water detected by the flow rate switch 40, and after confirming that the polarity of the voltage and each flow path have been inverted, the electrode 60C The application of a voltage to 17a and 17b is stopped, and an instruction signal is sent to the electromagnetic valve 30 to stop the discharge of the acidic ionized water. As a result, the discharge of the acidic ionic water is also stopped.

Here, since the polarities and connection flow paths of the electrodes 17a and 17b are in the second switching state as described above, when the user opens the water faucet 101, the electrolysis is performed. Al-ion water produced in the space 12 a in the tank 12 is supplied to the faucet via the second connection pipe 15 A and the fourth connection pipe 15 B via the Al-force water discharge pipe 14. It starts to be supplied at a predetermined flow rate from 100. At the same time, the electromagnetic valve 30 provided in the acidic water discharge pipe 15 is opened, and the acidic ion water generated in the space 12 b in the electrolytic cell 12 is discharged into the first connection pipe 14 A and The acid water is discharged from the outlet 120 through the acidic water discharge pipe 15 via the third connecting pipe 14B.

Then, when the user closes the faucet 101 again, and the control unit 60C obtains a signal indicating the stoppage of the discharge of the alkaline ionized water detected by the flow rate switch 40, the inverting means 5OA Reverses the polarity and reverses the connection flow path from the second switching state to the first switching state. That is, the polarity is reversed so that the electrode 17a becomes a positive electrode and the electrode 17b becomes one electrode, and the electromagnetic valves 31 and 32 are opened. Then, the electromagnetic valves 33 and 34 are controlled so as to be closed. As a result, when tap water is introduced again into the electrolytic cell 12, Al force water is generated in the space 12 b, and acidic ion water is generated in the space 12 a. Along with this, the alkaline ionized water is discharged from the faucet 100 through the first connecting pipe 14 A provided with the electromagnetic pulp 31, and the acidic ionized water is discharged from the second connecting pipe 15 provided with the electromagnetic valve 32. It will be discharged from outlet 120 through A.

As described above, in the present embodiment, the polarity of the voltage applied to each of the electrodes 17a and 17b is inverted for each interpal using the alkaline ionized water, and the connection between the alkaline water and the acidic ionized water is performed. The reversal of the flow path is repeated, and the functions of the electrodes 17a and 17b, the spaces 12a and 12b in the electrolytic cell 12 and the electromagnetic valves 31 to 34 are used alternately. Thus, in the present embodiment, the lifetimes of the electrodes 17 a and 17 b and the ion exchange membrane 16 are considered to be doubled as compared with the case where one of the functions is used continuously. . As described above, in the Al-Rion water purifier 10 C of the present embodiment, the Al-Lyr water spouting pipe 14 is linked to the reversal of the polarity of the voltage applied to the electrodes 17 a and 17 b. Since the connection flow path leading to the acidic water discharge pipe 15 is reversed, the ionized water is used as usual even when the electrodes 17a and 17b remain inverted. And each function can be used alternately at similar time intervals. This prevents impurities from adhering to one of the electrodes 17a and 17b and the ion-exchange membrane 16 and prevents the wear and operation burden of each function from being biased to one side. In addition to maintaining the water quality, it is possible to maintain the water conditioning capacity at the beginning of use for a long time.

In the fourth embodiment described above, the polarity and the connecting flow path were reversed when the discharge of the water was stopped, but the present invention is not limited to this. The time may be determined in advance, and the time may be reversed every predetermined time. In the above-described third embodiment, the polarity and the connection flow path are reversed at the same timing. However, the present invention is not limited to this. For example, when the faucet 101 stops, only the polarity is reversed. When the faucet 101 is opened again, the connection flow path is reversed. May be controlled as follows. In other words, the polarity reversal and the connection channel reversal need only be linked in a practical use state, and there is no need for the temporal timings to match, and the timing of each reversal may be appropriately controlled. .

Embodiment 4 described above may be applied to Embodiment 2 or 3 described above as it is.

(Embodiment 5)

FIG. 13 is a cross-sectional view of an Al-ion water purifier according to Embodiment 5 of the present invention. FIG. 14 is a side view of an alkali ion water purifier according to Embodiment 5 of the present invention. FIG. 1 is a schematic block diagram showing an operation example of an alkali ion water purifier according to Embodiment 5 of the present invention, and FIG. FIG. 2 is a schematic diagram showing a connection configuration of FIG.

In the present embodiment, while maintaining the generation ratio of the alkaline ionized water and the acidic ionized water at a constant level, the acidic ionized water is electrolyzed in a stepwise manner, thereby significantly reducing the prepared water concentration of the alkaline ionized water to be discharged. This is an example in which control is performed such that the discharge amount of acidic ionized water is greatly reduced without any problem.

In such control, the present embodiment is different from the above-described first embodiment in that the electrolyzer is configured and held in at least two or more stages inside the water purifier body 11D. . Specifically, this electrolytic cell consists of a first (previous) electrolytic cell (hereinafter referred to as a main electrolytic cell 12D) to which tap water is supplied, and an electrolytic cell generated in the first electrolytic cell. It consists of the second and subsequent (later stage) electrolytic cells to which acidic ionized water is supplied (hereinafter referred to as an auxiliary electrolytic cell 1 12 D). In the present embodiment, the electrolytic cell for supplying the generated acidic ionized water will be described as the first stage, and the electrolytic cell for supplying the acidic ionized water will be described as the second stage.

As shown in the figure, in the present embodiment, six electrolytic cells are provided side by side, of which five electrolytic cells on the right correspond to the main electrolytic cell 12 D of the first stage (front stage), and one electrolytic cell on the left. The dissolving tank corresponds to the second and subsequent (later) auxiliary electrolytic cells 1 1 2D. In the following description, the five electrolytic cells on the right side are collectively referred to as a main electrolytic cell 12D, and the one electrolytic cell on the right side is also referred to as an auxiliary electrolytic cell 112D.

The ratio of the processing capacity of the main electrolytic cell 1 2D to that of the auxiliary electrolytic cell 1 12 D In other words, the production rates of Al-Karion water and acid-ion water are almost the same. In this case, by making the generation ratio of the alkaline ionized water and the acidic ionized water 10: 2, the acid ionized water with respect to the alkali ionized water generated in each of the electrolytic cells 12D and 112D is minimized. It is possible to reduce the emission of acid ion water most efficiently.

In this embodiment, the branch pipe X is provided so that the alkaline water discharge pipe 14 and the acidic water discharge pipe 15 communicate with each other. An electromagnetic valve 30 b is provided in the middle of the branch pipe X. Thus, the electrodes 17a and 17b function when they are washed.

Here, the connection configuration between the electrolytic cells is specifically as shown in FIG. As shown in Fig. 16, the five electrolyzers on the right, namely the main electrolyzer 12D, are connected to the tap water supply pipe 13 on the downstream side so that tap water is supplied from the downstream side. At the same time, the upstream side is in communication with the water discharge pipe 14 and the water discharged from the main electrolytic cell 12D is discharged. Further, the upstream side of the main electrolytic cell 12D communicates with the acidic water discharge pipe 15 so that the acidic ion water generated in the main electrolytic cell 12D is discharged. Also, one electrolytic cell on the left side, that is, the auxiliary electrolytic cell 1 12D is provided in the middle of the acidic water discharge pipe 15 and the acid is introduced from the downstream side of the auxiliary electrolytic cell 1 12D to the inside. Water is supplied, and an auxiliary water discharge pipe 14b communicating with the water discharge pipe 14 is provided upstream. Alkaline water generated in the above is discharged.

In the AL-RION water conditioner 10 D having such a configuration, when the user opens the water faucet 101, the main electrolytic cell 12 D, that is, water is supplied to all of the five electrolytic cells on the right side. Water is supplied. Then, the supplied tap water is electrolyzed into alkali ion water and acid ion water in each main electrolytic cell 12D.

Then, the alkaline ion water generated in each of the main electrolytic cells 12 D is discharged from the faucet 100 through the alkaline water discharge pipe 14. On the other hand, the main electrolyzer 1 2 The acidic ion water generated in D is supplied to the auxiliary electrolytic cell 112D provided in the middle of the acidic water discharge pipe 15. The acidic ion water supplied here is electrolyzed again into alkaline ion water and acidic ion water in the auxiliary electrolytic cell 112D. At this time, in the present embodiment, in the main electrolytic cell 12D, with respect to 120 L of tap water of pH 7.1, 100 L of alkaline ionized water of pH 9.7 to 9.8 and ρ 84. Twenty liters of acidic ionized water consisting of 2 to ρ 、 4.5 are generated, and they are supplied from the faucet 100 to the spouting water or the auxiliary electrolytic cell 112D.

Then, the alkaline ionized water generated in the auxiliary electrolytic cell 112D is discharged from the faucet 100 through the auxiliary water discharge pipe 14b, the alkaline water discharge pipe 14, and the like. On the other hand, the acidic ionic water generated in the auxiliary electrolytic cell 112D is discharged from the outlet 120 through the acidic water discharge pipe 15. At this time, in the present embodiment, for 20 L of acidic ionized water composed of pH 4.2 to pH 4.5 generated in the main electrolytic cell 12 D, 16.7 L composed of H9.4 to 9.5 is used. 3.3 L of acidic ionic water consisting of the alkaline ionized water and the pH of 3.6 to 3.7 was generated, and these were discharged from the faucet 100 or discharged from the outlet 120. At this time, for example, the electrodes 17a and 17b may be cleaned by operating the electromagnetic valve 30b provided in the branch pipe X. In other words, when the water discharge is stopped, the polarity (10, 1) of the voltage applied to the electrodes 17a, 17b in the electrolytic cells 12D, 112D of each stage is reversed. To clean the electrodes 17a and 17b, and open the solenoid valve 30b so that the water from the water discharge pipe 14 moves to the acid water discharge pipe 15 side. However, all the water (water used for cleaning) in the electrolytic cells 12 D and 12 D of each stage may be discharged from the discharge port 120. In the water conditioner 10D, all the alkaline ionized water generated in the electrolytic cells 12D and 112D in each stage is discharged from the faucet 100, and the electrolytic cell in the last stage (in this embodiment, the auxiliary electrolytic cell Only the acidic ionized water generated in 1 1 2D) can be discharged from the outlet 120. In this embodiment, the acidic ionic water generated in the preceding electrolytic cell (main electrolytic cell 12D) is supplied to the subsequent electrolytic cell (auxiliary electrolytic cell 112D) to further supply the alkaline ionized water and the acidic ion water. Since water is generated, it is possible to reduce the amount of acidic ionized water finally discharged from the outlet 120.

As a result, in this embodiment, 16.7 L of alkaline ionized water consisting of pH 9.5 to 9.6 is discharged from the faucet 100 and ρ Η 3.6 to 3.7. 3.3 L of acidic ionized water consisting of Therefore, as compared with the conventional electrolytic cell structure having only one stage, the electrolytic cell structure including multiple stages as in the present embodiment can reduce the discharge amount of acidic ion water, for example, from 20% to 3.0%. It can be greatly reduced to 3%.

In the conventional apparatus, for example, a flow rate adjusting solenoid valve or the like is provided near the discharge outlet on the acidic ion water side to control the discharge amount of the acidic ion water. Since the discharge amount is relatively small at 3.3%, it is not necessary to install a flow rate adjustment solenoid valve near the discharge port 120.For example, one of the discharge passages in the acidic water discharge pipe 15 It is also possible to adjust the discharge of acidic ionized water by providing a resistance member or the like that blocks the section. As a result, the number of parts of the electromagnetic valve is reduced as compared with the conventional device, and the cost can be reduced.

In Embodiment 5 described above, the multistage structure of the electrolytic cell is exemplified by a two-stage electrolytic cell structure. However, the present invention is not limited to this. For example, a three-stage or four-stage electrolytic cell structure may be used. An electrolytic cell structure composed of steps may be employed. That is, any configuration may be used as long as the acidic ion water is electrolyzed stepwise on the acidic water discharge pipe 15 to generate alkaline ionized water and acidic ionized water. Similarly, in this case, the acidic ionic water generated in the preceding electrolytic cell is supplied to the latter electrolytic cell, and only the acidic ionic water generated in the latter electrolytic cell is discharged from the outlet 120. Will be.

Further, in the above-described fifth embodiment, it is assumed that the electromagnetic valve 30 is provided to reliably control the discharge amount of the acidic ionized water. The water may be naturally discharged from the outlet 120 with the discharge of the alkaline ionized water.

Further, the fifth embodiment described above can be applied to the second to fourth embodiments as they are. Good.

(Embodiment 6)

FIG. 17 is a schematic sectional view of an Al-Rion water conditioner according to Embodiment 6 of the present invention, and FIG. 18 illustrates each flow path in the electrolytic cell according to Embodiment 6 of the present invention. FIG. FIG. 18 schematically shows the inside of the electrolytic cell when FIG. 17 is viewed from the direction of arrow A.

The present embodiment is an example in which the electrolysis efficiency is improved without reducing the flow rate and the size of the Al-Lion water conditioner is reduced.

In such a configuration, in the present embodiment, by providing a plurality of folding plates 27 in the electrolytic cell 12 E, the flow path meandering at one end of the folding plate 27 and the other end The second embodiment is different from the first embodiment in that another flow path is formed.

Specifically, the ion exchange membrane 16 is held in the electrolytic cell 12 E by the fixing member 20 E provided with the folding plate 27, so that the two spaces 12 a and 12 b are formed. It is divided into A pair of electrodes 17a and 17b is fixed by a fixing member 20E in a region of the electrolytic cell 12E facing the ion exchange membrane 16. That is, in the electrolytic cell 12 E, the ion exchange membrane 16 and the respective electrodes 17 a and 17 b are integrally held by the fixing member 20 E provided with the folding plate 27. I have. The electrodes 17a and 17b are connected to the inner surface of the electrolytic cell 12E and the electrodes 17a and 17b by spacers 20e provided on the inner surface of the electrolytic cell 12E. A gap of 1 mm is formed between them. The electrodes 17a and 17b are electrically connected to the terminal 18 provided on the water purifier main body 11E by connection wiring 19.

Here, as shown in the figure, the fixing member 20E extends from the raw water introduction hole 26a of the electrolytic cell 12E to the Alion water outlet hole 26b and the acid ion water discharge hole 26c. It is composed of a pair of members provided on the 两 side of the width direction 201 orthogonal to the reference direction 200.

A plurality of folding plates 27 are held by the fixing member 20E at predetermined intervals via a holding member 28 over the reference direction 2.0. In the present embodiment, three folding plates 27 are provided at equal intervals on the fixing member 20E.

The holding member 28 holding the folding plate 27 is provided on the ion exchange membrane 16 side of the fixing member 20 E. And a pair of plate-like members constituting the fixing member 20E in the width direction 201, on each of the surfaces on the electrode 17a or 17b side. The folding plate 27 is held between a pair of holding members 28 provided on both sides of E such that the longitudinal direction thereof is the width direction 201. Such a folding plate 27 is formed to be shorter than the interval between a pair of plate members constituting the fixing member 20E so that both ends thereof do not contact the fixing member 20E. However, a part of the flow in the width direction 201 is restricted against the reference direction 200 of the tap water flowing in the electrolytic cell 12 E.

That is, the deflection plate 27 is alternately displaced to one end side of the width direction 201 so as not to abut the fixing member 20E, so that the deflection plate 27 in the width direction 201 of the deflection plate 27 is First flow paths 29a are alternately formed between the other end and the fixing member 20E. Further, since one end of the folding plate 27 is deflected so as not to abut on the fixing member 20E, the second flow path 2 is provided between the one end and the fixing member 20E. 9 b are alternately formed. Such a second flow path 29b is provided to be narrower than the first flow path 29a, and has a smaller flow rate than the flow rate of tap water passing through the first flow path 29a. And tap water is passing through.

Then, the tap water introduced from the power supply introduction hole 26 a into the electrolytic cell 12 E is converted into the first flow path 29 a defined by the folding plate 27 and the second flow path 2 a. Since it is provided wider than 9b, a meandering flow 210 is formed along the first flow path 29a. Further, since tap water also flows through the second flow path 29b, which is narrower than the first flow path 29a, the eddy current prevention flow 2 1 1 passing through the second flow path 29b is formed. It is formed. In other words, the tap water supplied to each of the spaces 12a and 12b from the raw water introduction hole 26a flows through the folding flow 210 and the eddy current prevention flow 211, and the alkaline ionized water flows. Outflow holes 26b and acidic ionized water outflow channels 26c flow out.

In the present embodiment, other configurations than the above-described configuration are the same as those of the above-described first embodiment, and thus description thereof will be omitted. Further, the basic operation of the alkali ion water purifier 10E is the same as that of the above-described first embodiment, and a description thereof will be omitted. As described above, in the alkali ion water purifier 10 E of the present embodiment, by providing the folding plate 27 in the electrolytic cell 12 E, the vortex 2 10 meandering in the internal flow path and the vortex are formed. By setting the flow prevention flow to 2 1 1, it is possible to prevent the occurrence of water stoppage in the electrolytic cell 1 2 E. Thus, tap water can flow over the entire surface of the electrodes 17a and 17b, and the electrolysis efficiency by the electrodes 17a and 17b can be improved. Thereby, even if the flow rate flowing through the electrolytic cell 12 E is increased, it is possible to reliably generate electricity from the tap water and generate alkali ion water. In addition, by narrowing the overlapping area in the width direction 201 of the adjacent flow plate 27, the meandering of the folding flow 210 is almost straight, and even if the meandering is gentle, the water is stopped by the eddy current prevention flow 211. Since no is formed, it is possible to prevent the pressure loss in the electrolytic cell 12E from being reduced in a state where the electrolytic efficiency is improved. This can prevent the flow rate in the electrolytic cell 12E from decreasing. In addition, since the flow rate can be prevented from being reduced in a state where the electrolysis efficiency is improved, the size of the electrolytic cell 12 E can be reduced, and the size of the alkali ion water conditioner 10 E can be reduced. Can be. The embodiment of the present invention has been described above. However, the basic configuration of the present invention is not limited to the above, and the following modified configurations are possible.

For example, in Embodiment 6 described above, the folding plate 27 is arranged in the width direction 201 orthogonal to the reference direction 200. However, the present invention is not particularly limited to this. For example, the folding plate 27 May intersect with the reference direction 200 and may be arranged so as to be inclined with respect to the width direction 201.

Further, in Embodiment 6 described above, the folding plate 27 is provided on the fixing member 20E in the electrolytic cell 12E. However, the present invention is not particularly limited thereto. The folding plate 27 may be provided directly without providing the fixing member 20E. In this case, for example, the electrodes 17a and 17b hold one surface of each of the folding plates of the spaces 12a and 12b, and the folding plates of the spaces 12a and 12b are held. On the other surface side, the ion exchange membrane 16 may be sandwiched, and the folding plates of the spaces 12a and 12b may be connected so as to penetrate the ion exchange membrane 16. As described above, the ion-exchange membrane 16 can be fixed only by the folding plate 27 without providing the fixing member 20E in the electroporation casket 12E.

Further, in the sixth embodiment described above, the first and second flow paths 29a and 29b are arranged by disposing the both ends of the folding plate 27 so as not to contact the fixing member 20E. However, the present invention is not limited to this. For example, it is possible to provide an opening that penetrates both ends of the folding plate so that both ends of the folding plate contact the fixing member 20E. Yo Alternatively, the first and second flow paths may be formed.

In the above-described sixth embodiment, the three flow plates 27 are provided in each of the first and second spaces 12a and 12b. However, the first and second spaces are provided. The flow rates of the first and second spaces 12a and 12b may be adjusted by changing the number of the flow plates 27 of 12a and 12b. In addition, the same number of folding plates 27 are provided in each of the first and second spaces 12a and 12b, and the overlapping area of the adjacent folding plates 27 in the width direction 201 is changed. May be used to adjust the flow rate. Embodiment 6 described above may be directly applied to Embodiments 2 to 5 described above.

FIG. 19 is a cross-sectional view of an Al-ion water purifier according to Embodiment 7 of the present invention. FIG. 20 is a cross-sectional view of a main part of an alkali ion water purifier according to Embodiment 7 of the present invention. It is.

The present embodiment is an example of configuring an alkali ion water conditioner that can be used for medical and cosmetic purposes by easily and surely adding power calcium to raw water.

In such a configuration, the present embodiment differs from the first embodiment in that a power calcium addition chamber 160 that is branched from the tap water supply pipe 13 and can be filled with calcium from the outside is provided.

Specifically, the tap water supply pipe 13 is provided with a branch 150 that is branched from the tap water supply pipe 13. The branch 150 is formed by a cheese 130 serving as a joint between the raw water pipe 100 and the tap water supply pipe 13.

Further, on the branch 150 side of the cheese 130, a calcium addition chamber 160 is provided in which a calcium compound 15 1 having one end communicating with the branch 150 is held. The calcium addition chamber 160 has an opening 161 on the opposite side of the branch passage 150 so as to be freely opened and closed with respect to the outside. Examples of the calcium compound 151 held in the calcium addition chamber 160 include highly safe calcium compounds recognized as food additives such as calcium lactate and calcium glycerophosphate. In the present embodiment, a calcium holding member 1 made of a mesh bag is used. By holding calcium compound 15 1 in 52 and placing calcium holding member 15 2 in calcium addition chamber 160, calcium compound 15 1 is held in calcium addition chamber 160 I did it. In this way, by holding the calcium compound 15 1 by the cal-pum holding member 15 2, when the tap water enters the calcium addition chamber 160, the calcium compound 15 1 Can be added in a desired ratio.

Further, on the calcium addition chamber 160 side of the branch 150, a sealing member holding part 162 having an inner diameter larger than that of the branch 150 is provided. A sealing member 170 having a spherical shape is movably held in the sealing member holding portion 162. Since the sealing member 170 has an outer diameter larger than the inner diameter of the branch passage 150, movement toward the raw water pipe 100 is restricted.

Further, a communication hole 163 having an inner diameter smaller than that of the sealing member 170 is provided on the calcium addition chamber 160 side of the sealing member holding portion 162, and the communication hole 163 is formed. The sealing member holding part 162 and the calcium addition chamber 160 communicate with each other through the intermediary of the sealing member. When the sealing member 170 comes into contact with the opening edge of the opening 163 on the side of the sealing member holding portion 162 of the through hole 163 to seal the communication hole 163, tap water is supplied. A seal member 164 is provided to prevent the calcium from entering the chamber 164. Examples of the material of the sealing member 164 include metal, plastic, rubber, and elastomer. Examples of the material of the sealing member 170 include metal, plastic, rubber, and elastomer.

Here, since the water pressure regulator 10 F of the present embodiment is directly connected to the raw water pipe 100, the tap water is always supplied at a predetermined water pressure in the tap water supply pipe 13. Supplied. For this reason, the sealing member 170 is urged toward the communication hole 163 by the water pressure of the tap water supplied from the raw water pipe 100 unless a force is applied from above, so that the calcium addition chamber 1 The 60 openings are sealed.

One end of the sealing member 170 is fixed to the sealing member 170, and the sealing member 170 is in contact with the sealing member 164 of the communication hole 163. There is provided a rod-shaped pressing member 171 provided so that an end protrudes from the opening 161 of the calcium addition chamber 160 by a predetermined amount. Further, a lid member 165 is removably fitted to the opening 161 side of the calcium addition chamber 160, and the lid member 1665 is connected to the calcium addition chamber 160 The opening 161 is sealed. In the present embodiment, the lid 165 is screwed into the opening 161 side of the calcium addition chamber 160 to seal the calcium addition chamber 160.

When the opening 161 of the calcium addition chamber 160 is sealed by the lid member 1665, the other end of the pressing member 171, which projects from the opening 161, is lowered by the lid member 165. , And the sealing member 170 is moved to the branch 150 ° against the water pressure from the raw water pipe 100. As a result, a gap is created between the sealing member 170 and the calcium addition chamber 160, and one end of the calcium addition chamber 160, that is, the communication hole 163 is opened. Then, from the opened communication hole 16 3, tap water from the raw water pipe 100 intrudes into the calcium addition chamber 160 by water pressure, and the calcium compound 15 1 in the calcium addition chamber 16 0 Calcium is diffused into tap water upon contact. And the tap water to which calcium is added is a tap water supply pif. Supplied to the electrolytic cell 12 via 13;

At this time, the size of the gap between the sealing member 170 opening the communication hole 163 and the communication hole 163 is determined from the opening 161 of the calcium addition chamber 160 of the pressing member 171. Is determined by the amount of protrusion. The flow rate of tap water entering the calcium addition chamber 160 is determined by the size of the gap between the sealing member 170 and the communication hole 163. For this reason, the amount of protrusion of the pressing member 17 1 from the opening 16 1 may be appropriately determined so that the amount of calcium added to tap water has a predetermined ratio.

Here, the addition of potash to tap water and the filling of the potash compound into the potash addition chamber 160 will be described in detail. FIG. 20 is a cross-sectional view of a main part of an AL-force water regulator 10F showing a method of adding and filling calcium. First, as shown in Fig. 20 (a), when the lid member 165 is removed from the opening 161 side of the calcium addition chamber 160, the sealing is performed by the pressure of tap water supplied from the raw water pipe. The member 170 is pressed to the calcium addition chamber 160 side and abuts on the seal member 16 4, and the sealing member 170 seals the communication holes 1, 63 to form the calcium addition chamber 160. Seal one end. As a result, tap water in the raw water pipe 100 cannot enter the calcium addition chamber 160, and tap water leaks from the opening 160 of the calcium addition chamber 160. Can be prevented. Then, in this state, the calcium compound 151 is filled into the calcium addition chamber 160 from the opening part 161. At this time, the other end of the pressing member 171, one end of which is fixed to the sealing member 170, protrudes from the opening 161 by a predetermined amount.

Similarly, when the calcium compound 151 in the calcium addition chamber 160 has been used up, the calcium compound 1501, in the calcium addition chamber 160, with the lid member 165 removed, is also provided. Can be replenished.

As described above, when the lid member 165 that closes the opening 161 of the calcium addition chamber 160 is opened, the sealing member 170 is closed at one end by the water pressure of the tap water. The tap water does not leak from the opening 16 1 of the calcium addition chamber 160, and the calcium compound 15 1 can be easily and reliably filled into the calcium addition chamber 160. .

Next, as shown in FIG. 20 (b), when the opening 161 of the calcium adding chamber 1650 is sealed with the lid member 165, the lid member 165 is pressed by the pressing member 171 The sealing member 170 is pressed against the tap water pressure via the, and the sealing member 170 is moved to the raw water pipe 100 side. Thereby, the communication hole 163 on one end side of the calcium addition chamber 160 sealed by the sealing member 170 is opened. At this time, the tap water supplied from the raw water pipe 100 intrudes into the calcium addition chamber 160 by water pressure, and contacts the calcium compound 1501 in the calcium addition chamber 160, so that calcium is supplied. Is added. Then, the tap water to which the potassium hydroxide is added passes through the communication hole 16 3 and is supplied to the electrolytic cell 12 via the tap water supply pipe 13.

In this way, the sealing member 170 is pressed downward by the pressing member 171 just by closing the opening 161 of the calcium adding chamber 160 with the lid member 165, so that calcium is added. One end of the chamber 160 can be opened, and calcium can be easily and reliably added to tap water. Note that, in the present embodiment, the configuration other than the above-described configuration is the same as that of the above-described first embodiment, and a description thereof will not be repeated. Since the same applies to the first embodiment, the description thereof is omitted.

As described above, in the alkali ion water purifier 10 F of the present embodiment, when the lid member 165 that closes the opening 161 of the calcium addition chamber 160 is opened, the sealing member 170 One end of the calcium addition chamber 160 is closed by the water pressure of the tap water, so that the tap water does not leak out from the opening 161 of the calcium addition chamber 160, and the calcium compound 1501 is added with calcium. The chamber 160 can be easily and reliably filled. Further, by simply closing the opening 161 of the calcium addition chamber 1660 with the lid member 1665, the sealing member 170 is pressed by the pressing member 171, and one end of the calcium addition chamber 1610 is closed. It can be opened and calcium can be easily and reliably added to tap water.

In the above-described seventh embodiment, one end of the pressing member 17 1 is fixed to the sealing member 170, and the other end is pressed against the lid member 16 5. For example, one end of the rod-shaped pressing member may be fixed to the lid member, and the other end may be brought into contact with the sealing member so that the sealing member is pressed downward by the pressing member fixed to the lid member. Good. Further, in Embodiment 7 described above, the sealing member 170 is a member having a spherical shape. However, the present invention is not particularly limited to this. For example, a hemisphere in which the side abutting on the sealing member 164 is formed as a spherical surface It may be shaped.

Further, in the above-described Embodiment 7, it is assumed that tap water to which calcium is added is filled in the space between the electrolytic cell 12 and the water conditioner main body 11. On the water pipe side, a cheese for branching the raw water pipe may be newly provided, and the tap water to which calcium has not been added may be filled in the space between the electrolytic cell 12 and the water conditioner main body 11. In this case, an electromagnetic valve that opens and closes based on a signal from the flow rate switch 40 may also be provided in the water pipe to which the tap water filled in the water regulator body 11 is supplied. As a result, wasteful consumption of the calcium compound 151 can be prevented, and the cost can be reduced.
